+  Params can also be given rates. By default, they are :kr, however
+  another rate can be specified by using either a pair of [default rate]
+  or a map with keys :default and rate:
+
+  (defsynth foo [freq [440 :kr] gate [0 :tr]] ...)
+  (defsynth foo [freq {:default 440 :rate :kr}] ...)
+
   A doc string can also be included:
   (defsynth bar
     \"The phatest space pad ever!\"

   name default pairs, name [default rate] pairs or a vector of maps:

  (defsynth foo [freq 440] ...)
  (defsynth foo [freq {:default 440 :rate :ar}] ...)

  Returns a vec of param maps"


  These can also be abbreviated:
  (foo :tgt 2 :pos :head)

  [s-name & s-form]
  {:arglists '([name doc-string? params ugen-form])}
